“We are looking for a special person to establish this new customer care operation and immediately grow it 100 people per year for several years,” the ad reads. The director position would report to a Squarespace vice president.

The company appears to be considering other cities, too. Squarespace tweeted last week that “We’re opening a left coast customer care office in 2014.” It asked its Twitter followers, “Where should we go? Portland, Seattle, Vegas, Boulder…or somewhere else?”

We’re opening a left coast customer care office in 2014. Where should we go? Portland, Seattle, Vegas, Boulder…or somewhere else?

Portland appears to be a front-runner, judging by Squarespace’s local real estate search and its job listings. The company has no listings for jobs in Colorado or Nevada; it does seek a customer care manager in Seattle, and one in Portland – in addition to the Portland customer care director.

Founded in 2004 in a University of Maryland dorm room, Squarespace provides tools for building and hosting websites and blogs. The company says it has 238 employees and raised $38.5 million in 2010.

If it does come to Portland, Squarespace would be the latest in a long series of tech companies based elsewhere to open large Oregon offices.

Intel is the biggest example – the California company’s largest operations anywhere are in Washington County. But many other big names, from Hewlett-Packard to IBM to Xerox – have key offices in Oregon.
